Homotopy algorithm

Hello,

I have a question relative to the homotopy algorithm used by the unstable version of Dynare to solve perfect-foresight models.

I am running a code which calls Dynare in a cycle solving my model under different calibrations.
I would like to keep track of when the homotopy algorithm fails in solving my model. I was therefore wondering in which Dynare variable/structure is
this information stored?

Thanks in advance for your time
